With recent announcements of successful vaccine trials, perhaps the central ethical question of the pandemic is how to fairly and equitably distribute vaccines as they become available. This episode considers the principles that ought to govern the distribution of Covid-19 vaccines, and the ways that existing models and plans fail to show equal moral concern for those most vulnerable to harm. My guest is Florencia Luna, Director of Bioethics at the Latin American Faculty of Social Sciences (FLACSO) in Argentina.
